Many modern land drains are created utilising rigid or flexible plastic pipes pierced with holes, laid in pea gravel. (The pea gravel is pea-sized pebbles without sharp points to damage the pipe.) Geotextile material can surround the gravel to keep out silt.
Land Drainage is used to remove excess water from fields and gardens, in fact any area where excessive water is a problem.
The perforations allow seeping water to ingress the pipe, capillary action then maintains the water within the pipe allowing it to flow to its destination i.e. Storm water Attenuation Tanks, also known as Modular Plastic Geo Cellular Units (egg crates) or a watercourse (stream, lake etc. ).
Land Drainage Features
- Perforated and coiled land drainage pipe is manufactured in HDPE.
- Normally used in agriculture and in building construction sites.
- Particularly beneficial in areas with heavy ground conditions i.e. clay.
- Relieves hydrostatic pressure.
